I'm trying to process events using the X toolkit in a way that will not
block when the queue is empty.  This is what I'm doing:

  XEvent event;

  while (XtAppPending(context)) {
    XtAppNextEvent(context, &event);
    XtDispatchEvent(&event);
  }

However, this seems to block when there are no events in the queue.  Am
I doing something wrong, or is this a bug?
